Okay so here's the problem. I haven't had a problem during the summer with anything but squirrels but now that the temps are way down below 0 I have a bunch of rats that have moved from the woods behind my house into my barn and are living in the room where I store my horse hay. It is hard if not impossible to get at them but I do often see them when I go out. I talked to the guy at the feed store and he suggested that I put out rat bait but switch the brand and the look of the bait once a week so that they don't get used to what it looks like and associate it with getting sick or dying. That worked for a total of 3 rats that I found inside the coop dead but other than that I am still seeing them. Tonight I went into the coop and there was one on the side of the water bucket drinking. I actually tried to grab it by the tail as it ran away but it made it to the other side of the barn and into the hay before I could get him. I put the bait right where I saw him walking. We also set some snap traps but I can't put them in the coop with the chickens because I don't want to hurt them with it so we have to put them in the hay room instead and where we can put them might not be where they go. The worst possible thing is that since I saw the rats for the first time I have been getting at max 3 eggs from 19 hens. I am pretty sure they are taking the eggs and eating them during the day while I am at work. Any suggestions for how to help get rid of them quickly without hurting my hens in the process?
